预计2012年至2050年期间,对动物蛋白的需求将增加70-80%,而目前的动物生产部门已经造成了重大的环境退化。食用昆虫被认为是一种更可持续的动物蛋白质来源。然而,关于昆虫生产对环境影响的实验数据很少。因此,对黄粉虫生产进行了生命周期评估,其中量化了温室气体产生、能源使用和土地使用,并与传统的动物蛋白质来源进行了比较。从牛奶、鸡肉、猪肉或牛肉中生产一公斤可食用蛋白质会导致更高的温室气体排放,需要类似数量的能源,并需要更多的土地。这项研究表明,粉虫应该被认为是一种更可持续的食用蛋白质来源。
The demand for animal protein is expected to rise by 70–80% between 2012 and 2050, while the current animal production sector already causes major environmental degradation. Edible insects are suggested as a more sustainable source of animal protein. However, few experimental data regarding environmental impact of insect production are available. Therefore, a lifecycle assessment for mealworm production was conducted, in which greenhouse gas production, energy use and land use were quantified and compared to conventional sources of animal protein. Production of one kg of edible protein from milk, chicken, pork or beef result in higher greenhouse gas emissions, require similar amounts of energy and require much more land. This study demonstrates that mealworms should be considered a more sustainable source of edible protein.
